JFK is a route that is often oversold with a lot of shuffling between different flights. If BA needs to roll people forward to fill the plane then they will. Chances are you go lucky under the algorithm and there is no guarantee you get upgraded again. I'm sure you'll find plenty of status holders who have been overlooked for upgrades in favor of people like yourself (I.e..non status holder),
